To all 'whom if mayconcema. `Y

Be it known that'I, JOHN A. SOH'UL'rz, J r., acitizen of the United States, residing at Newark, in the county-ofEssex'and State of New Jersey, have `invented:certain new fand useful Improvements in'Ap-paratus for Filling Siphon-Bottles, of lwhich the following is a specification, reference being had therein to the accompanying drawings, which form apart thereof.

My invention relates to apparatus for ll`- 'ing siphonl bottles, and more particularly to a type thereof adapted to charge the bottle with carbonio Vacid gas prior to the delivery of the charged Vfluid thereinto;

Themain object of my invention isto provide an apparatus' of this character wherein the carbonic acid gas, substantially uninixed with air, may be charged into an empty siphon bottle prior to the delivery of charged water thereinto, and the apparatus continued in use for an extended period, using the carbonio acid gas repeatedly without material deterioration in the quality of such gas.

A further object is to provide an apparatus of this character, wherein the siphon may. be snifted or vented'into the tank containingrthe carbonio acid gas, and said gas tank will be automatically vented to maintain a substantially constant, `uniform pressure therein.

A still further object is to provide an apparatus of this character wherein' carbonio bottle, thereis a gasto escape than under normal conditions. VTo ob-viate this diiiiculty, the atmospheric acid gas only will be delivered to the siphon bottle from the gas tank, and any water discharged into said tank when the bottle is snifted or vented will be automatically discharged from the tank,thusV preventing the delivery of flat `water to the siphon with the initial charge of gas, and insuring quality of the bottled uniformity iii the water.

A still further object is to providean api paratus of this character wherein anyairA discharged into thefcarbonzic acid gas tank, maybe discharged fromsa-id tank from time to time, t-o prevent the accumulation of air in` this tank and a resultant initial charging of the bottlel therewith, alone or in subi stantial volume mixed4 with the gas. And a still further object isto provide an appa? ratus of this character, of simple design fand y so constructed and arrangedas totake ad?` f pressure is sufficiently low to bonic acid gas, and air in the gas tank, to insure'the delivery of substantially purecarbonic acid gas to the siphon bottle.

The invention consists in the novel features of construction and combination of parts hereinafter set forth and described and hereto appended.

In the accompanying drawing I have shown a front elevation of an apparatus einbodying my invention, the carbonio acid gas tank being shown in vertical section to dis`- close the interior arrangement thereof.

In the art of lling siphon bottles, water previously charged with carbonio acid gas. under pressure ranging from one hundred to two hundred pounds is, in some instances, delivered from a tank to the bottle, prior to the filling of the bottle, valve being arranged in the pipe line between the filling nozzle and the water tank to destroy the equilibrium of pressure in the bottle and in the tank when the bottle is partially filled, and to permit the completion of the filling of the bottle with the desiredV gas pressure upon the top thereof. There is a constant tendency of the gas to particularly pointed out in the claims a vent or snift escape from the water when the surrounding permit it to escape, andas the charged water is delivered tothe bottle lled with air, there is asu'iicient loss of the gas to lower the quality of the bottled goods. Furthermore, as the water is sprayed through the siphon tube into the still greater tendency of the air in the bottle may be displaced by air mingled with pure carbonio acidgas under low pressure, or by gas alone, and thus not only minimize the tendency of the gas in the `water to esca-pe therefrom, but provide a vol- `ume of carbonio acid gas through which the `incoming water is discharged 1n a spray and tliuscause said water, if it has not already absorbed' gals to its full capacity, to take up additional gas and thus raise its quality.

The herein described apparatus is so de'- signed' as to deliver gas to the siphon bottle Ainsuch'Condit-ion as to insure high efficiency in the above described process, and to permit Vthe iilling of' a large number of bottles with- 'outI'substantir-ill variance in the condition of the water therein.

vantage of the stratification'of water, car? 1 Intheembodment of my inventionshown in the drawing, which is merely one application thereof, however, adapted to be used in connect-ion with two bottling machines, I have shown at a, a bottling machine of any well known, or approved type provided with a combined filling valve I) and snift valve ZJ connected respectively through the pipe c' with the water tank or carbonator, not shown, and by the pipe d, with a low pressure carbonio acid gas tank c which may be supported upon a separate standard, as shown, or by the standard of the bottling machine, as desired, the manner of mounting said tank relative to the machine being immaterial to the invention.

The tank c interiorly thereof is free from obstruction so as to permit the automatic separation and stratification of the air, carbonio acid gas, and water, delivered to the tank while in use, the specific gravity of the three varying in the order named, water being the heaviest.

To insure the delivery of carbonio acid gas with as little air as possible therein, I draw the supply of gas passing through the pipe d from a point slightly above the bottom of the tank e, through the tube f, the upper end of which projects through the top of the tank and is providedwith a fitting g adapted to coperate with the pipe cl. The lower, open end of the tube f, it will be observed, is vthus disposed within that portion of the tank wherein the carbonic acid gas will stratify, any mixture of air and gas, being of lower specific gravity than the unmixed gas, risinv above this point,

and thus affording sufficient time for the gas and air to separate and the latter to rise to the top of the tank, a construction made desirable by reason of the fact that with the filling of the bottle, air, or a mixture of carbonio acid gas and air, with or without water, is delivered to the tank e through the tube 7, the pipe Z being connected with the snift valve of the syphon filling machine. Ilie open end of the tube f will also be positioned above the bottom of the tank e sufficiently to prevent the water accumulated in the bottom of said tank being forced through the snift valve into the bottle being filled.

Mounted in the top of the tank e is a three-way fitting l1, the leads of which are respectively connected with a pressure gage y z', a vent or pet cock j and a union member 7c adapted to be connected with a carbonio acid gas tank for the purpose of fillingthe tank@ with carbonic acid gas or replenishing the Supply of such gas therein. rIhe fitting 7L opens into the tank e at the topthereof, so-

tliat the upper strata of air may be vented through the pet cock y', thus preventing the accumulation of air within the tank e in delivered to the siphon bottle through the tube f. The fitting 71,-, adjacent vto the union member L, is provided with an ordinary c ut y o valveZ for limiting the supply'of gas `charged into the saidrtank." I liavefshownV at m a second tube similar to the'tubej'f,

which permits the tank e to be coupled to another filling machine at the same time.

As the bottle is sniftedJ7 a certainaniount of water is carried over into the tankefand this water accumulates in the bottom of the tank, and the carbonio acidgas previously taken up thereby is disassociated or released from the water to an extent to cause this water to become flat andunpalatable,

` this resulting from theldiiference in the pressure between the water tank and the tank e.

' This water accumulates in the tank e fairly rapidly, and with the accumulation of this water, the pressure in the tank is gradually' raised beyond that necessary to secure thehighest efficiency of the apparatus. This also varies the conditions underwhich suc-V ceeding siphons are filled, so as to result ina variance in the quality of the bottled water. To obviate this condition, I provide a trap pipe n having an automatic blow off valve o so set as to operate at substantially that pressure desired` within the tank e,

thus causing the raising of the pressureV within the tank to automatically operate this valve to relieve such pressure by the blowing off of the water accumulatedin this trap and in the bottom of the vtank e. I c provide the blow off valve o with a fitting p Y which may either open into atmosphere or be connected with a gasonieter, if it be desired to separate the gas and water and save the former. I have found in practice that the venting of the tank e from the bottom thereof is the most effective and mostV economical in use, although the tank may be vented at any other point thereof if desired.

The operation of the herein described apparatus is substantially as follows: Assuming that the gage shows a low, or no, pressure in the tank e, the valve Z is first opened to admit carboiiic acid gas to said tank, this gas, the bottle is set in the bottling'machine Y inthe usual manner and the Siphon v-alve opened, the bottle being inverted soV as to permit the filling and snifting7 of the bottle through `the tube thereof.

The

snift valve b is then opened to permit y i the carbonio acid gas, .underthe low pressui'e maintained in the tank e, to flow into the. bottle and displace the atmospheric air contained therein although this may be either mixed with the infiowing gas, or flowback into the tank e. When the pressure in the tank e and theA bottle are equal, the sniftv7 valve is closed and the-iillingr valveopened to` admit wateri charged with gas under relatively higher pressure than that of the tank e, to flow intoJ thebottle. The inflowing water is. thus delivered to the bottle against il pressureA of carbonio `acid, `gas of approximately forty pounds, this. having the twofold result: of preventing the escape of the gas previously absorbed, ortaken up, Vby thewater, and causing anywater insufficijontlycharged towtake` up. gas as it is sprayed 'through the gas `contained in the bottle... As the pressure in; the bottle'is.

raised until it; equals that upon the water in the tank, the equilibrium of pressure preventsthefurtherflow of waterto the bottle, thusmaking it necessary to relieve the pressure the bottle to insure the filling thoreof; To destroy this Vequilibrium of pres-A sure/the shift valve Zi is again opened'V and the mixture-` of Agas-upon the topi` of the water isvented through the piped, being discharged into the tank e; The pressure in the bottle having thus been` lowered, the 'll- 251 u to the bottom of the tank e, and the mixed' ing valve ZJ is again opened and the valves b and b are alternately opened and closed until the desired quantity of water under the desired pressure isin the bottle. As the snift valve b is. opened, a mixture of air and gas with a. small quantity of water carried in suspension therewith, is delivered tothe tank 6 passing;Y downwardly through` the tubeA The water by reason of its greater specific gravity immediately drops gases havin lower s oeciic @ravit than the c g l a Y carbonio acid gas` in the tank; e, rise aboveV the open end of the tubef where theY air and gas become disassociated; the air rising to` the topiof thetank and the gzuifent-ering` the gas stratum adjacent tothe open end of said tube f. My experiments indicate that this separation or disassociation` of the carbonio' acidV gas and air is not instantaneous, re

quiring but ay small interval of time, however; but by drawing the carbo-nic acidA gas delivered: tothe bottles from a point interniediatethe top and the bottom of the tank e, l secure a substantially pure carbonio acid gaaunmixed with aiigand provide a` zone within the tank c within which this separa;

tion may occur without impairing the cllif oiency of the machine. -Inasmuch as the pressure within the bottle, when it is sniffed, is greater than that within. the

tank c, the gases and air-discharged into the tank e will gradually raise the pressure in this tank. Before,however, there has been.

a sufficient increase of the pressure to vary the-conditions under'which the apparatus operates, the valve @will behopened and the pressure within. the tankfrelieved, restoring the pressure in saidl tank to normal. As

heretofore stated, this blowing off operation is aocompaniedby a discharge of any water accumulated in the tank e, and it is not acconipanied by a substantial loss of gas ever though a gasometer is notl used. Afterthe machine has been in use for some time, say for half a day, the pet cock j should be opened and the pressure within the tank c reducedby the blowing od of the air accumulated inthe topi of said tank, the pressure within the tank being subsequently raised by the admission of fresh gas thereto, upon the opening of the valvel Z,

In the foregoing description l have used the term pure carbonio acid gas 7 to indicate merely a high quality of commercial gas, and have used the word gas to indicate carbonio acid gas as distinguished from the air.

It is not. my intention to limit the invention to the precise details of construction shown in the accompanying drawings, such being merely a showing of one application Aof the invention` which is capable of being varied without departing from the spirit orl .under pressure `relatively higher than the normal pressure in said supplemental tank, and with said supplemental tank intermediate the top and bottom thereof, whereby substantially pure carbonio acid gas is delivered from said tank, said valve mechanism being so set that `said bottle is alter* nately placed iii` communication with said supplemental tank and with a carbonated" water tank, whereby the carbonio acid gas Vfrom said tank is alternately discharged `from said tank into said bottle and from said.v bottle back into said tank.
